The three train together, spend time off the court together and, most importantly, have the same competitive mindset.

“Right now, they’re competing against each other,” said Wizards coach Flip Saunders. “They’re playing a lot of point guard, and I think all three of them are in good shape.”

The starting backcourt is Wall at point guard and Crawford at shooting guard, with Mack as the primary backup to play either spot. The advantage Saunders has is that all three can play both positions.

“There’s no question that for Shelvin, playing against John and his speed and quickness has facilitated his progress as far as being able to initiate an offense and vie for some time at the backup point spot,” Saunders said.

Wall and Crawford began developing their chemistry last year, but Mack believes he’s fitting in. Mack and Wall also have known each other since college.

“We’re working out together each and every day off the court,” Mack said. “We hang together off the court and play video games. I think our chemistry is going really well together.”

As for their on-court work, Wall said that the three of them have their own mini-shootaround after practice.

“We try to get shots up together just to have that chemistry and talk the whole time,” Wall said. “We have fun. In the locker room, we chill.”

But while Wall, Crawford and Mack continue working and playing together, the elephant in the room is the status of free agent Nick Young. He was the starting two guard last year until a left knee injury put him on the bench and Crawford in the starting lineup.

Young is a restricted free agent, and the Wizards have given him a qualifying offer of $3.7 million. Young still is weighing his options.
